> The disposable income calculator works out disposable personal income – gross income minus income taxes and payroll taxes – per year and per month, and how it splits between spending and saving.

## Inputs

- Gross income
- Income taxes (federal, state, local)
- Payroll taxes (FICA)
- Saving per year

## Results

- Disposable income
- Per month
- Consumption spending
- Saving rate
- Total tax rate

## Formula

```
Disposable income = gross income − income taxes − payroll taxes (Social Security, Medicare)
Personal saving rate = saving ÷ disposable income
```

## Explanation

Disposable income is what households can spend or save. The U.S. personal saving rate has averaged around 4–6% of disposable income in recent years (BEA).

### How to use the Disposable Income Calculator

- **Gross income**
- **Income taxes (federal, state, local)**
- **Payroll taxes (FICA)**
- **Saving per year**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter gross income, income taxes, payroll taxes and your planned saving.

### Tips

- Use real (inflation-adjusted) figures to compare across years.
- Check whether data are seasonally adjusted.
- Use the same currency and base year throughout.
- Economic models simplify reality – treat results as illustrations, not forecasts.

### Common mistakes to avoid

- Mixing nominal and real values.
- Comparing percentage changes with percentage-point changes.
- Treating correlations as causes.

### What each result means

- **Disposable income** = [Gross income] - [Income taxes (federal, state, local)] - [Payroll taxes (FICA)]
- **Per month** = [Disposable income]÷12
- **Consumption spending** = [Disposable income] - [Saving per year]
- **Saving rate** = [Saving per year]÷[Disposable income]×100
- **Total tax rate** = ([Income taxes (federal, state, local)] + [Payroll taxes (FICA)])÷[Gross income]×100

### Example values

How the main result changes when **Gross income** changes and everything else stays at the example values above:
